Application nea .nach 22, 190B. sapin No. 307,430.

I of the United States, residing at Boston, inthe county of Suffolk andState o Massachusetts, have invented certain new and useful Improvementsin Tires, o which the following is a specification. i

This invention relates to an improvement in vehicle tires, andparticularly to a tire oi the cushion type which shall combine themaximumresiliency and' durability While at the'sa'me time avoiding theobjections incident to the usual pneumatic tire.

The tire oi the present invention is m'ade up of a plurality 'oftransversely alranged sections constructed of materials of varyingdegrees-of resiliency, the less` resilient sections serving as areinforce and brace for the more resilient sections. o i

The invention will be .described inthe following specilcation, referencebeing` had particularly to the accompanying drawings, in which1- Figurelis a broken perspective of a tire constructed in accordance withmyinvention, illustrating particularly the transversesectional-formation of the tire.

Fig. 2 is a broken longitudinal section oi the tire. Fig. 3 is a similarview showing. a modified construction o tire, Fig. 4 isa view oi atireshowing solid sections.

' 'Fig. 5 is a detail longitudinal section oi the same.`

Referring particularly to the drawings, nity improved I Vtiro isconstructedI of a plurality oi-sections l and 2,

arranged'transversely of and alternately throughout the length of thetire. `By preference, the -sections Y' 1, are composed of a relativelyhigh resilient material,- as rubber, while the sections 2, are composedof a ma terial of less degree of resiliency, as leather, fibrousmaterial or' the like. Each section is formed with an opening, whereby`to provide a channel extending longitudinally of the tire when saidsections are assembled. The openings are eccentric -to the outer contourof the sections, to provide a thickened surface adjacent the tread, andi-preferred end projections 3, may bel employed to engage beneath thesecuring flanges o the wheel telly. The channel is lined with a hollowresilient or like lining 6.

The sections l and 2, are to be arranged alternately throughout thelength oi the tire withtheir contacting surfacesl cemented or otherwisesecured together, to provide a solid body formed oi transverselyarranged sections alternately disposed, sotthata relatively non--resilientV section will be effective as a. brace and reinforce for aresilientsection.

In Fig. 3, I have illi. -trated a modified form in which the relativelynon-resilient sections are in effect cornposed of duplicate strips 4, ofthe same material secured together, adding materially to the reinforcingTIRE vSpecification of Letters Patent.

effect.

` Patented muy e, iso?.

The tire structure is inclosed in an envelop 5, pref- -erably of rubber,or the usual tire covering, which envelopmay be of `anydesired sectionalformation, preferably howeverkbeing constructed to give the greatestthickness at the tread portion of thetire. In the use or" the envelopand lining G, as a covering for the' tire construction described, it ishighly desirable that an effective binding be secured between thesections and envelop -or covering.- To secure this bind- .ing I preferto vulcanize the tire structure and lining, lthereby'providing ineect'an integral body, including the lining, and resilient sections ofthe tire proper, the relatively non-resilient sections, oi course, beingunaffected by the vulcanizing process. v A tire constructed as abovedescribed possesses a high degree of resiliency without depending uponany pneumatic principle, being therefore free of difiiculties arisingIfrom punctures. It has the further` advantage of being cheaplyconstructed, and owing to the useo'i the relatively non-resilientsections, is very durable.

Whilepreferring to use rubber and leather as' the material for thesections, it is of course, obvious, that .these materials may berespectively replaced by others having similar characteristics, as thedesired element in the construction is the usc of arcsilient section inconnection with a section oirelativoly non-resilient material which willin effect brace and reinforce thc resilient section euren under loadstrain.

As shown in Figs. 4 and 5, the tire is composed oi rubber sections l,and leather sections 2, but omitting the openings therein, the cover 5,incasing the assembled sections,l i

Having thus described the invention what is claimed as new, iszi 1. vAtire composed' of transversely arranged sections of rubber and leather',and a covering for the sections, said covering being vulcanized to therubber-sections.

2. A tire comprising alternate. sections of a resilient and relativelynon-resilient material, a covering for said sections, and a lining vforthe sections, snld covering and lining Abeing vulcanized to'theresilient sections. 3. A tlre composed of transversely arrangedalternately disposed sections of rubber and leathdr,'each.of saidsections being iormed'wth iin-opening, a. covering for the sections, alining tting the opening in the sections, said covering and lining beingvulcanized to the `rubber sections.

4. `A tire comprising alternately arranged sections of a CII 6. A tirecomposed of transversely arranged sections of rubber and material ofless degree of resiliency than the rubber sections and formed withopenings to provide a channel, a resilient element within thechannel, aresilient cover for the sections, said cover and said resilient elementbeing vulcanized to the rubber sections.

T. A tire composed of resilient and relatively non-resilient sections ofmaterial, said non-resilient sections being formed of a plurality ofstrips of material connected together and disposed in parallel relationto the resilient sections, and a covering for 'the sections vulcanizedto the resilient sections.

S, A tire comprising alternately disposed sections of a resilient andrelatively non-resilient material, the non-re silient section comprisingva plurality of strips secured together, and a covering for thesections, said covering being vulcanized to the resilient sections.

9. A tire composed of transversely arranged sections of resilientmaterial and interposed non-resilient material,

ing for the channel, and a resilient cover for the sections,

said cover being vulcanized to the rubber sections to bind the tiretogether.

1n testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
